Best Client Portal Software (2026): Top 9 Compared

SuiteDash describes itself as all-in-one business software, combining more than 25 toolkits behind one login: CRM, onboarding, projects, file sharing, proposals, invoicing, scheduling, email marketing and a client portal. The pitch to service firms is consolidation, replacing several single-purpose subscriptions with one system that is branded as the firm's own.

SuiteDash's documentation treats the portal as the authenticated environment around everything a client is allowed to use. Firms present it with their own logo, colours and custom URL, and can show each client a dashboard assigned directly, by circle or team, or by role, with a fallback dashboard for everyone else. Portal pages carry resources, announcements or personalised content, and an assigned page can become the first screen after sign-in. The documentation notes that an account can have one custom URL, which requires a DNS record.

Pricing is the main distinction. Plans are priced per account rather than per user, and SuiteDash lists unlimited staff, unlimited contacts and unlimited portals on the entry plan. Thrive adds proposals, drip marketing, deal pipelines and client-side live chat. Pinnacle adds the automation toolkit, onboarding flows, a learning management system, support tickets and task dependencies.

Assembly is the client portal company formerly called Copilot. It renamed itself in September 2025, explaining that the Copilot name had become hard to find once Microsoft and GitHub used it for AI assistants. Assembly's own update states that existing client portals and custom domains kept working through the change.

The product combines a CRM for the firm's team with a branded client experience on the firm's domain. Clients message the team, share files, sign contracts, complete tasks and pay invoices in one place. Assembly ships more than 30 ready-made apps covering intake, onboarding, proposals, payments and project tracking, and each can be adapted. An AI app builder creates new apps from a written description; Assembly states that sign-in, permissions and data isolation remain platform infrastructure rather than generated code, that each app runs in its own sandbox, and that the company holds SOC 2 Type II certification.

Pricing is set by active client contacts and internal users. Build credits are consumed only when the AI builder creates or edits an app, not when clients use a live app. Firms with regulated data should note that the HIPAA business associate agreement appears on the Advanced plan.

Clinked sells white-label client portal software for secure collaboration, and states that more than 3,000 businesses across 40 countries use it. Its customers are typically firms that handle sensitive client documents and want the portal to look entirely like their own product.

Each client gets a workspace for files, tasks, approvals, messages and project updates. Clinked lists version control, document watermarking, full-text search, group and one-to-one chat, Kanban boards on Premium, and migrations from SharePoint, Dropbox and Box. Integrations named on the pricing page include DocuSign, Adobe Acrobat Sign, Power BI, Google Workspace, Microsoft OneDrive and Jotform, and Clinked states access to more than 7,000 integrations through connectors such as Zapier.

The plan structure is unusual. A per-user Start Up plan covers very small teams, while Standard and Premium are flat monthly prices that include a fixed number of members. Enterprise adds the white-label mobile app, Active Directory and single sign-on, uptime SLAs and data centre choice. Clinked also sells a separate virtual data room product with redaction, dynamic watermarking, NDAs and Q&A for transactions.

Moxo positions its portal as the place where client work moves forward rather than a dashboard where documents sit. Each relationship can get its own branded portal: clients see one, vendors see another, and each runs its own processes. Firms choose which elements a portal offers, such as flows, AI chat, resources and service requests.

The client side is designed to remove friction. Moxo states that clients need no account, password or download and open one secure link on any device. Inside, they complete document requests, forms and uploads, give e-signatures and approvals, book meetings and video calls, pay invoices and pass identity checks. An AI concierge answers status and next-step questions so staff do not have to.

Behind the portal sits Moxo's workflow engine. The pricing tiers add sub-flows, business rules, branching, loops and scheduled flows, along with preparer, reviewer and advisor agents that draft documents, check submissions for completeness and handle follow-ups. Moxo's customer stories name Savills for commercial property deals, Palmetto for solar customer onboarding and Emirates Bank for wealth clients, which places it toward larger organisations.

FuseBase describes itself as AI-native client portal software and states that it has operated since 2014 and is used by more than 3,000 businesses. Its product splits into an internal workspace for the team and external workspaces, which are the client portals.

The design argument is that a portal that looks like a project management tool goes unused by clients. FuseBase therefore builds portals as protected microsites with the firm's branding, on the view that clients already know how to navigate a website. Each portal can include pages, file sharing, real-time updates and client-facing apps, and FuseBase presents portals for onboarding, ongoing client service and partner or deal spaces.

The internal side includes task management, Kanban boards, calendars, dashboards, content templates, chat, comments and workflow automation, plus AI agents and transcription quotas. Pricing scales by members, portals and clients rather than storage alone, so the Solo plan suits a single practitioner with one client relationship and Essentials covers up to 100 clients. White label and granular permissions and groups are listed from the Advanced plan, which is the tier most agencies reselling a branded experience would need.

ShareFile began as a secure file-sharing service and has grown into a document workflow platform; it is now a Progress Software product. Its client portal is aimed at firms whose client relationship runs on documents: tax returns, engagement letters, statements and contracts.

ShareFile's portal page focuses on ending the client chase. Clients see dashboards of the active items, tasks and documents that need attention, submit files against document request lists, and receive automated notifications so staff do not have to follow up. Files and messages are encrypted and limited to authorised users. Firms can add their logo and colours, create portals for unlimited client users, and point clients to the ShareFile for Clients mobile app on iOS and Android. ShareFile also states that it walks clients through account setup.

Integrated e-signature, workflow automation and forms sit on the Premium plan alongside the enhanced client portal, and Premium is the tier ShareFile recommends for firms that work with clients and need a secure portal. Industry Advantage adds pre-built templates and bulk client onboarding for tax engagements. Pricing counts staff users only, with a three-user minimum.

TaxDome is practice management software for accounting, tax and bookkeeping firms, and the client portal is one of its central components rather than an add-on. The portal and mobile app carry the firm's branding, and TaxDome states that firms can customise the URL, login page and automated system emails.

Within a job, clients can complete an intake form, upload documents, approve or e-sign documents and engagement letters, message the firm securely and pay. TaxDome reports more than 1.2 million jobs completed in 2024, more than 400,000 documents e-signed, more than 300,000 proposals and engagement letters signed, and more than $500 million in invoices paid through the platform.

The rest of the system covers an unlimited CRM, ready-made workflow automations, integrated email, SMS and chat, proposals and payments. Pro adds an IRS transcript integration, general ledger connections for bookkeepers, AI reporting, account roles and a managed firm website. Business adds Client Care, in which TaxDome's support team answers clients' platform questions, plus seasonal seats and client import assistance. Pricing is per seat per year, so the cost scales with staff rather than clients.

Plutio is all-in-one business software for freelancers and small teams, and it includes a client portal on every plan. Plutio frames the problem as hours lost to status emails, scattered files and invoices held in separate tools, and the portal as the place where clients find all of it.

Each client sees a branded space with live project progress and task status, shared files, the message thread and full invoice history with a payment button for anything outstanding. Plutio states that clients reach the portal through a unique link sent with their first invoice or proposal, or through the firm's custom domain, and do not need a Plutio account or a download. Firms control visibility per client: some get full project and file access, others see only invoices and payments.

Around the portal, Plutio includes unlimited projects, invoices, proposals and contracts with e-signatures, time tracking, scheduling, forms and Kanban, list, calendar and Gantt task views, with payments through Stripe, PayPal or Square. Plans differ by active clients, contributors, AI credits, workflow actions and storage rather than by features, which keeps the comparison simple for a solo operator deciding when to move to Pro.

Softr is a no-code application builder, and client portals are one of its main use cases. Rather than selling a fixed portal, it gives a team drag-and-drop blocks and a data layer from which to build one. Softr states that more than one million teams use the platform.

The data model is the main distinction. Softr connects natively to its own Softr Databases and to Airtable, Google Sheets, Notion, HubSpot, monday.com, ClickUp, MySQL, Postgres and Supabase, plus a REST API connector, and syncs those sources in real time. A firm that already tracks clients and projects in Airtable or a CRM can expose that data to clients without migrating it.

Softr's portal page lists the building blocks: sign-up and login pages with conditional onboarding forms, account management, in-portal messaging and comments, document upload and e-signature requests, shared project timelines and tasks, invoices and payments through Stripe or PayPal, embedded dashboards and a resource hub. Portals can be turned into a downloadable mobile app. Pricing counts builders and app users, with client users defined as those outside the builders' email domain, so firms should check app user limits on each plan against their client count.
